SOLE ROUNDING AND CHANNELING MACHINE.-

v I SPECIFIGATION formingpart of Letters Patent N 0. 649,125, dated May8, 1900.

Application filed October 20,1899.

Be it known that I, HANFORD T. CROSBY, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Sole Rounding and Channeling Machines, of which the fol-This invention relates to machines for rough rounding and channeling thesoles of boots and shoes while on the last; and it has for its object toprovide a machine of this and adjusting the principal working parts.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation of a sole rounding and channelingmachine embodying my invention. Fig. 2 represents an elevation takenfrom the opposite side. Fig. 3 represents a front View. Fig. 4represents a rear view, partly in secof Fig. 1. Fig. 6 represents afront view of portions of the machine. Fig. 7 represents a section online 7 7 of Fig. 6. Figs. 8 and 9 are sectional views showing differentadjust- Fig. 10 represents a perspective view of the work-rest, thechanneling-knife, and the channelingknife holder. Fig. 11 represents asection on line 11 11, Fig. 10. Fig. 12 represents a bottom view of achanneled sole.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, a represents a work supporting and guiding Wheel, whichis formed to enter the crease between the welt and upper, said wheelbeing preferably serrated on its face, which bears-on the welt. Thewheel a is affixed to-a shaft Z), which is jour-, naled in a fixedbearing on the supportingframe 0 and is connected with the drivingshaft(Z by a Worm e on said driving-shaft and-a worm-gear f on the shaft 6.

Adjacent to the inner side of the wheel a is a fixed cutting bed orblock g, which cooperates with a reciprocating rough-rounding knife orchisel h. Said knife is affixed to a slide or carrier 6, which ismovable in a guide Seria1N0. 734,213. (No model.)

'7', hereinafter referred to. The carrier 1' is connected by a rod iswith an eccentric wrist- 'pin 3 on the driving-shaft d. The knife h isdetachably secured to the outer end of the carrier '5, which is splitand provided withdovetail shoulders 11' t", Fig. 6, between which theknife is clamped by means of a clamping bolt 11 in thesplit end of thecarrier. The guide j has a s1eevej Fig. 5, which is fitted to turn on astud j, affixed to the frame 0, the guide being thus made verticallyadjust able to vary the distance between the lowest portion of the wheela and the cutting edge of the knife, and therefore the width of theprojecting portion of the sole outside the bottom of the'welt-crease.The guide is held at the desired vertical adjustment by means of a screwj, Figs. 1 and 3, engaged with a tapped socket in the frame and passingthrough a slotted ear 7' on an arm 7' formed on the guide and nuts j",engaged withsaid screw and bearing on opposite sidesof the ear 3' I 9'is a fixed vertical ear or guide, which has a sliding fit between thearm 7' and a corresponding ear f, Fig. 3, formed on the guide j, thesaid ear j steadying the guide j and preventing crosswise movementthereof.

Z represents a rest or support for the face of the sole, which isadjustable horizontally toward and from the wheel a to accommodate anydesired thickness of sole. The rest Z is attached to a slide Z, which ismovable horizontally toward and from the wheel a in the guide t and isnormally projected and held yieldingly with the rest Zat the minimumdistance from the wheel ct by means of a spring Z attached at one end toa stud Z on the frame 'of the machine and at its other end to a stud onthe slide Z. The rest Z may be retracted against the stress of thespring Z by abell-crank lever Z pivoted at Z to the frame, and a rod Z,connecting one arm of the lever Z to a treadle, (not shown,) the otherarm of the lever Z being engaged with the slide Z.

The channeling-knife'm is affixed to anarm or carrier m, which has acompound connection with the rest-carrying slide Z, so that thechanneling-knife moves horizontally with the rest Z toward and from thewheel a and is adapted to reciprocate horizontally in a direetionparallel with the feed movement of the sole to cut the channel thereinand to move vertically toward and from the roughrounding knife it whilereciprocating horizontally to vary the distance between the channel andthe edge of the sole, as shown in Fig. 12, where the mouth 1' of thechannel is shown farther from the edge of the sole 8 at the shank thanat the fore part. The said compound connection, as here shown, comprisesan angular block n, to which an car an on the rear end oftheknife-carrying arm m is connected by a horizontal pivot n, whichpermits the arm m and channeling-knife m to be adjusted verticallytoward and from the rounding-knife h. The base of the block at isconnected by a vertical pivot nF'with the rest-carrying slide Z, saidpivot permitting the block it and the arm m, with the channeling-knife,to oscillate horizontally, the pivot 91. also causing the block n, armm,

.and channeling-knife m to move, with the slide Z, toward and from thewheel (t.

The means employed to reciprocate the arm m and knife on horizontallycomprise a camslot 0 in the rounding-knife slide '5 and a stud m on anarm m formed on the arm m, said stud entering the cam-slot 0, which isformed to impart a short reciprocating movement to the arm m and knife min a direction substantially at right angles to the movement of theslide 2' and rounding-knife h.

Means are employed to raise and lower the channelingknife while themachine is in operation, the reciprocating movement of the knife beingunaffected by the vertical adj ustments thereof. Said means comprisealever p, pivoted at Z to the frame and having at one end abearing-screwp, and a rod 13 connecting the other end with a treadle.(Not shown.) The screw p bears against the lower end of a plate or slideg, which has a limited verti cal movement on a vertical face on theframe 0 and is secured to said face by screws q q,

passing through vertical slots (1 g in the plate q, said slots beingshown by dotted lines in Fig. 2. The plate g has horizontal ears q (1between which the channeling-knife arm m has a sliding fit and isadapted to oscillate horizontally. The plate q is normally held at itslowest position by a spring q, connecting one of the ears (1 with a studg on the frame 0, the channeling-knife being thus held at the maximumdistance from the rounding- Tknife, Fig. 8. \Vhen the lever 19 is movedby the depression of the treadle connected therewith, the plate q israised and its ears (1 cause the arm m to swing upwardly on the pivotor, thus adjusting the channeling-knife toward the rounding-knife, Fig.9, the horizontal reciprocating movement of the channeling-knife arm mcontinuing between the ears g (1 The extremes of the vertical movementsof the ehannelingknife may be determined by adj ustablc stop-nuts it ona screw- .threaded rod 15', which is connected with one of the ears Therod '6 passes through a fixed car i on the frame a, one of the nuts 25being above and the other below said ear.
